Features 1. Wide voltage range of 3-24V, compatible with a variety of devices 2. Integrated start/stop switch for more convenient operation 3. Real-time speed display for clear status monitoring 4. Made with high-quality materials for guaranteed durability 5. Precise speed control for 4-wire fans, combining quiet operation with stability Parameter DC 3-24V Power Supply 3-pin power supply and PWM signal output LED indicator showing speed percentage Digital display showing speed percentage When connecting a servo or brushless ESC: Fixed PWM frequency of 50Hz Speed control adjusts the positive pulse width within the range of 0.95-1.95ms There are 3 configuration solder points on the back for mode selection, as follows: 1. Default Mode No configuration; speed is adjusted via the knob; buttons have no function 2. Power-On Start Mode Short the power-on start configuration points; after power-up, the motor starts at the knob-set speed after a 3-second delay (simulating manual throttle adjustment from 0 to the set speed). Suitable for scenarios where the ESC needs to spin the motor to a specified speed immediately upon power-up 3. Switch Start Mode Short-circuit the switch start configuration points. The motor will not start upon power-up; it will wait until a button or external switch is pressed. Note that the button must be held down or the switch short-circuited for the motor to operate; releasing the button will cause the motor to decelerate. Suitable for scenarios requiring an external switch to control motor rotation/stop. Package include Mainboard *1 188 LED display *1 3-pin bent header *1 10K potentiometer *1 Potentiometer cap *1 label:yes
